Optical illusion producing amusement device
Abstract
An optical illusion producing amusement device in which a
resilient transparent tube that has first and second ends is held
in a circle defining configuration by a plug that engages the
interior surface of the tube when the first and second ends are in
abutting contact. The plug also serves the further function of
engaging first and second end portions of a light reflecting ribbon
disposed within the tube. The ribbon has first and second sides of
first and second colors, with the plug maintaining the ribbon in
the form of a spiral whereby both the first and second colors are
visible to a viewer. When the device is rotated the eyes of the
viewer are concurrently subjected to moving areas of both the first
and second colors, and an optical illusion is produced that the
device is of a third color intermediate the first and second color.
In a second form of the device, a rigid rod is secured in a
diametrically extending position within the confines of the circle
defining tubing. The rod is preferably ornamented with spiral
defining areas of first and second different colors. The form of
the device that includes the rod permits the device to be twirled
as a baton.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
An optical illusion producing amusement device.
2. Description of the Prior Art
In the past, various types of circular members have been
manufactured and marketed, such as the well known "Hula-Hoop," for
the entertainment of users, primarily children. In devices of the
type above mentioned the entertainment is derived by the skill of
the user in causing the circular member or hoop to spin or rotate
on a desired part of a user's body.
The primary purpose in devising the present invention is to supply
an amusement device that may be employed by the user to rotate on a
desired portion of a users body, but also one that when spun
provides an optical illusion due to the rapid rotation of elongate
alternate first and second areas of different colors that are
visually distinct from one another, and the device as it rotates
imparting the optical illusion that it is of a third color that is
intermediate between the first and second colors.
Another object of the invention is to provide a device that is
formed from standard commercially available materials, is
inexpensive to produce, and one that may be modified to a second
form to include a diametrically extending rod that permits the
device to be used as a baton.
A still further object of the invention is to furnish a rotatable
amusement device that has all or a portion of the features
previously mentioned and in addition including a number of small
noise producing bodies within the confines of the device, which the
bodies produce noise when moved relative to the portion of the
device in which they are contained.
SUMMARY OF THE INVENTION
An optical illusion producing amusement device that includes a
length of transparent resilient tubing that is deformed into a
circular configuration to have first and second ends thereof in
abutting contact. A light reflecting elongate ribbon having first
and second sides of first and second different colors is disposed
within the tube in a spiral configuration, and the first and second
colors being concurrently visible to a viewer.
A cylindrical plug is provided that has first and second portions
that fit snuggly into the interior of the tubing adjacent the first
and second abutting ends, with the plug having slots or other
fastening means formed therein, and the plug serving the dual
function of holding the first and second ends of the transparent
tubing in abutting contact as well as hold the first and second
ends of the ribbon in fixed positions relative to one another to
prevent the tubing from unwinding from its spiral defining
configuration. The device above described when rotated provides an
optical illusion that it is of a third color intermediate between
the first and second colors.
A second form of the invention includes the device above described,
but with the circle defining tubing having a diametrically
positioned rod disposed within the confines thereof. The rod is
secured firmly to the tubing, with this rod permitting the device
to be twirled as a baton.
The rod may have spiral defined areas thereon that are of different
color and preferably colors that match the first and second colors
of the ribbon. Although it is preferable to have the first and
second colors defined by a spiral wound ribbon within the confines
of the tube, the same effect can be achieved on the second form of
the invention by having first and second ribbons of first and
second colors spirally wound on the exterior of the tubing in edge
to edge relationship with one another as well as on the rod.

invention; and
FIG. 6 is a fragmentary longitudinal cross sectional view of the
second form of the invention taken within the oval shown in phantom
line in FIG. 5 and identified by the numeral 6.
DESCRIPTION OF THE PREFERRED EMBODIMENT
A first form A of the invention as may be seen in FIGS. 1 to 4
inclusive includes a length of transparent resilient tubing 10 that
is deformed into a circle as shown in FIG. 1, with a first end 12
of the tubing being in abutting contact with a second end 14
thereof as shown in FIG. 4. The tubing 10 is preferably formed from
a polymerized resin which when bent is capable of assuming the
circular configuration shown in FIG. 1. The interior surface 16 of
the tube 10 adjacent the first and second ends 12 and 14 is snuggly
engaged by a cylindrical plug 18 formed from wood or like
material.
The plug 18 serves to hold the first and second end portions 12 and
14 together in abutting contact. The plug 18 has first and second
transverse slots 20 and 22 formed on first and second end portions
thereof. A light reflecting ribbon B is disposed within the
confines of the tubing 10, which ribbon is colored first and second
contrasting colors 24 and 26 on opposite sides thereof as shown in
FIG. 3, with the ribbon B being twisted into a spiral configuration
within tubing 10. When the ribbon B is disposed in this spiral
configuration, the first and second colors 24 and 26 are
concurrently visible as shown in FIG. 3, and add a decorative
appearance to the first form of the device. It will be particularly
noted that the plug 18 serves the dual function of holding the tube
A in a circular defining position, as well as anchoring opposite
ends of the ribbon B in fixed relationship with one another, all as
shown in FIG. 4.
To prevent the ribbon B from crumbling when twisted into a spiral,
the ribbon is preferably formed with longitudinally spaced,
transverse extending, corrugations 28 as shown in FIG. 3.
The device A may be used in a manner such as the well known
"Hula-Hoop," and it may be spun by the user. When the hoop is spun
to slide along a ground or floor surface or roll thereover an
optical illusion is achieved due to the concurrent rotating of the
first and second colors 24 and 26, with the device taking on a
color that is intermediate between the first and second colors.
Ultimately, as the device spins in frictional contact with the
ground or floor it will frictionally engage the ground or floor to
the extent that the device will return to the user.
In a second form A-1 of the invention as shown in FIG. 5, the tube
10' is formed into a circle by the manner above described, and the
external surface of the tubing being covered with spirally wound
bands 30 and 32 that are of different colors and impart the same
optical illusion to a viewer as that achieved by the ribbon
previously described when second form A-1 is rotated. The second
form A-1 includes a diametrically disposed rod 34 situated within
the confines of the tubing 10' and rigidly secured thereto.
The rod 34 may be covered with spirally wound strips of material 30
and 32 that are of contrasting colors. The second form A-1 of the
invention may be used as a baton, when the rod 34 is held by a user
in a baton twirling position. To further enhance the entertainment
value of the second form A-1 of the invention the interior of the
tube 10, may have a number of small metal balls 34 or other movable
noise making devices disposed within the interior thereof.
The use and operation of the various forms of the invention have
been described previously in detail and need not be repeated.
